Gridview/DetailsView/EmptyData

[geo039]

Okay okay this is killing me. I have a gridview with a footerrow to add rooms to the selected value of bldg. When there are no rooms I dropped a detailsview in the emptydatatemplate. I wanted to use the same code I have so the user doesn't have to deal with bldgid but nothing is working. Any ideas how I can accomplish this task, maybe I need to redo everything. Footer row says this and works

Protected Sub gridLocations_RowCommand(ByVal sender As Object, ByVal e As GridViewCommandEventArgs)
 
        If e.CommandName = "Insert" AndAlso Page.IsValid Then
 
            ' Insert new record
            Dim roomnum As String = CType(gridLocations.FooterRow.FindControl("txtAddRoom"), TextBox).Text
            Dim bldgid As Integer
           TextBox).Text
 
 
            AddNewRoom(roomnum, bldgid)
 
        End If

If I do this in the emptydatatemplate it doesn't find dvAddRoom. If I take it out and put it under the gridview it finds it but....it still won't let me just take the selected value it says bldgid can't be null

Protected Sub dvAddRoom_ItemCommand(ByVal sender As Object, ByVal e As DetailsViewCommandEventArgs)
 
        If e.CommandName = "Insert" AndAlso Page.IsValid Then
 
            ' Insert new record
                        Dim roomnum As String = CType(dvAddRoom.FindControl("NewRoom"), TextBox).Text
 
 
            Dim bldgid As Integer
                      bldgid = gridBldgLoc.SelectedValue
 
            AddNewRoom(roomnum, bldgid)
 
        End If
    End Sub
